How do I solve the water control puzzle with some buttons erased?

  • 1 of 10: This panel works the same as its counterpart across the plateau...
  • 2 of 10: ... but with less information provide.  The erased buttons make it difficult to know where all four "water" ideograms are located.
  • 3 of 10: But the clue is still the same -- the four "water" ideograms just all be in separate rows and columns.
  • 4 of 10: Begin with the two "water" ideograms that are still identified.  (These would be in column 1, row 1 and column 3, row 2).
  • 5 of 10: Those two buttons account for the "water" ideograms in columns 1 and 3.  But there must be a "water" ideogram in all 4 columns.
  • 6 of 10: Three of the buttons in column 2 are clearly identified.
  • 7 of 10: So the "water" ideogram in that column must be the bottom button (C2R4).
  • 8 of 10: And since there must be a "water" ideogram in every row (as well as every column), you have now satisfied rows 1, 2, and 4, and columns 1, 2, and 3.
  • 9 of 10: Therefore, the final "water" ideogram must be in row 3 (the only row still missing a "water" ideogram) and column 4 (the only column still missing a "water" ideogram).
  • 10 of 10: Hence, the four buttons needed to solve this second water control puzzle are found as follows: 
           column 1, row 1
           column 3, row 2.
           column 2, row 4
           column 4, row 3
    Again, note how each column and each row is represented exactly once.
